Issues starting up with DDR5 RAM at 6000 MHz – functions okay at 4800 MHz, newest BIOS applied
Problem: My computer sometimes struggles to start up. It turns on but shows no screen, and the DRAM check indicator remains active. Resetting the CMOS helps for a short time. It appears the issue is linked to the EXPO profile on my DDR5 RAM, which operates at 6000 MHz. Notably, it doesn’t happen when running at the standard 4800 MHz. Details: Processor – AMD Ryzen 7 7700 8-Core, CPU Cooler – EK AIO Basic 240 77 CFM, Motherboard – MSI MPG B650I EDGE WIFI Mini ITX AM5 (latest BIOS), Memory – G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL36, Storage – Western Digital Black SN770 2 TB M.2-2280 PCIe 4.0 X4 NVME SSD, Video Card – NVIDIA Founders Edition GeForce RTX 4080 16 GB. Power Supply – Corsair SF750 750 W (80+ Platinum). I think the speed mismatch with DDR5 RAM might be causing the problem. The latest BIOS should help, but I’d love advice or someone’s experience with this setup or similar issues. Thanks!
I have that exact same memory. With the 7700X I had and the 7800X3D I have now, it has been perfect. Runs 6000MHz without issue. The 7700 should have the same memory controller as the 7700X, I would assume. Does it not boot, or take a long time and maybe you aren't waiting it out? Memory training is a thing in DDR5. There is a setting for Memory Context in the BIOS to flip, to help with it.
Thanks for your prompt reply! The problem seems to be unpredictable. It sometimes starts up immediately, other times it takes a long time or doesn’t boot at all after waiting over ten minutes. The DRAM indicator also appears occasionally. I haven’t checked memory training yet, so I’ll consider that next.
The time is probably too much. With various motherboards, you might need to adjust the RAM settings directly in your BIOS. It could be worth a try.
The DRAM indicator must activate each time. Debug LEDs function by showing which stage of the boot process is active, and if the sequence halts due to an issue, the corresponding LED remains illuminated. Try reverting to earlier BIOS versions (1-2). It's common for revisions to fail memory support on certain boards, so the latest update might have a problem with DDR5 6000.
